Answer:
Sample Question: What is the effect of molecule size on a molecule's ability to diffuse across a semipermeable membrane?
-format: “What is the effect of X on Y?”
-independent variable: molecule size
-dependent variable: the ability to diffuse across a semipermeable membrane
Answer:
The correct match would be:
- Swallow - migration
- Tiger - sparse distribution—scarce
- Devil’s Hole pupfish - local endemic
- Humpback whale - sparse distribution—widely dispersed
Swallows are small migratory birds belonging to the family Hirundinidae found all around the world. Migrating swallows can cover around 200 miles in a day.
Tiger has become endangered species due to excessive hunting and habitat loss. It is estimated that only 3800 tigers are left in the wild.
Devil’s Hole pupfish is a species of a fish only found in Devils Hole which is a geothermal aquifer-fed pool located in Ash Meadows National Wildlife Refuge in Nevada city of the United States
The humpback whale or <em>Megaptera novaeangliae</em> is a species of baleen whale which is widely distributed in all major oceans including Pacific, Atlantic, and Indian oceans.
Answer:
gene flow is the transfer of genetic variation from one population to another.
option D
Answer:
1) abiotic synthesis of small organic molecules (monomers)
2) joining of monomers into polymers
3) packaging of these molecules into protobionts, droplets with membranes that maintained a distinct internal chemistry
4) origin of self-replicating molecules that eventually made inheritance possible
